Thus Google still need Apple for one thing... oh and for WebKit (Google do work for chromium but what about webkit itself??? Apple engineer have to made WebKit 2 in order to have the tab isolation of chromium...)

1. WebKit is open source
2. WebKit is a fork of KTHML from KDE
3. Apple just hosts and administrates the project, WebKit is actually "developed" by multiple parties
4. If people get tired of Apple policies, they can fork WebKit or back-port all changes to KHTML and continue that path
